    2017 Discovery TDV6 HSE Aintree Green

    I changed both camshft pulleys at belt change, as there have been instances on the V6 where they 'disintegrate' with the resultant catastrophic damage, For the cost of them it was a no brainer, £125 the pair.

    So the previous owner decided to save some money and take a risk last year by not doing the belts.


    Replacing the belts (especially the rear) seems like an engine-out service and isn't called for on the TD6 engine in the maintenance specs? I'm at over 90k on my 2017 and seems to be running fine. What are the symptoms? In a gas engine I would expect rough idle and stumbling, screeching sounds, sluggish acceleration, smoke, and poor fuel economy, but in a diesel, as long as the engine gets cranked and the HPFP is fine, the SCR and general diesel compression ignition cycle should mask all of this until it fails?

    I think the spec is to change both belts at 7 years or 110k.

    It possible it will run fine for another 6 years or so, but as you say it's all fine until the belt snaps, then it's too late to change it.

    So for a few hundred pounds it's worth doing every 7 years, in my opinion.

    Had mine done last year… not an engine out job!!

    They did it in-situe.

    It looks like starter motor off and a lot of bending and twisting but, as you say, not an engine out job.

    Taking the starter motor off to access the timing hole in the flywheel is the hardest part, especially if you're lying underneath it instead of raising it up on a lift...that and having a capable assistant turn the engine over with a socket and breaker bar as you pop the locking pin in there.

    I was tempted to cheat and just paint a white line on the crankshaft... without locking the flywheel...but common sense prevailed and I did it properly. Whistle

    The fuel pump belt is easier than it looks, it's tucked away at the back of the engine next to the bulkhead but it's easy enough fitted with a bit of faffing about lying on the rocker cover to get in there. You might have to loosen and move the cross-over pipes and a few bits and pieces to get better access, apart from that, it's not too bad.

    Thanks Mole,

    I've had to put it of for one reason or another, hoping to get on it next Sunday.

    I'll let you know how we get on.
